Abstract

A flat colour selection electrode 15 is tensed on a supporting frame 17. In order to compensate for differenc­es in thermal expansion between the supporting frame 17 and the colour selection electrode 15 and mislanding, spring constructions 18 are placed between the supporting frame 17 and the colour selection electrode 15 and are connected to the colour selection electrode 15. Said spring con­structions should permit only a maximum tension at the colour selection electrode 15 which is smaller than the elastic proof stress of the colour selection electrode 15. Such a colour selection electrode 15 may be used in a colour display tube having an at least substantially flat display screen.
